8 p, 1.4 MB Enhanced arsenite removal by superparamagnetic iron oxide nanoparticles in-situ synthesized on a commercial cube-shape sponge : adsorption-oxidation mechanism / Lou, Xiang-Yang (Universitat Autònoma de Barcelona. Departament de Química) ; Boada, Roberto (Universitat Autònoma de Barcelona.

Hypothesis: The easy aggregation of superparamagnetic iron oxide nanoparticles (SPION) greatly reduces their adsorption performance for removing arsenic (As) from polluted water. We propose to exploit the porosity and good diffusion properties of a cube-shaped cellulose sponge for loading SPION to reduce the aggregation and to develop a composite adsorbent in the cm-scale that could be used for industrial applications.

Magnetic resonance imaging (MRI) is a useful tool for disease diagnosis and treatment monitoring. Superparamagnetic iron oxide nanoparticles (SPION) show good performance as transverse relaxation (T) contrast agents, thus facilitating the interpretation of the acquired images. [...]

18 p, 105.4 KB Arsenate removal with 3-mercaptopropanoic acid-coated superparamagnetic iron oxide nanoparticles / Morillo Martín, Diego (Universitat Autònoma de Barcelona. Departament de Química) ; Faccini, M. (LEITAT Technological Center (Barcelona)) ; Amantia, David. (LEITAT Technological Center (Barcelona)) ; Valiente Malmagro, Manuel (Universitat Autònoma de Barcelona. Departament de Química) ; Pérez González, Gustavo (Universitat Autònoma de Barcelona. Departament de Química) ; Aubouy, Laurent (LEITAT Technological Center (Barcelona))
In the present work, superparamagnetic iron oxide nanoparticles (SPION) surface-coated with 3-mercaptopropanoic acid (3-MPA) were prepared and their feasibility for the removal of arsenate from dilute aqueous solutions was demonstrated. [...]
